Hi! I've seen a bit of discussion about blind testing here recently, so I wanted to share a small browser-based tool that I've written, which allows you to do your own audio blind test (i.e., you can load audio files and listen to them in a randomized order that you don't know until you want to): https://nyxl.de/audioblindtest/ I originally wrote this to check if I'm actually able to hear a difference between quality settings of a plugin or if I was just imagining the difference (it turned out I could hear a difference). However, it can be used for any kind of blind testing, be it comparison of different audio compression methods, comparison of different reverbs as in https://tinyurl.com/ycxdtzay or other things. One restriction is that all audio files should have the same length, since you could identify the audio files from the length displayed in the audio players otherwise (it would be possible, but not trivial, to hide the time in the player, but I actually find that useful if I want to listen to a certain section of the files). I've made some screenshots from an mp3 vs wav comparison: https://nyxl.de/audioblindtest/testimages/demo01.png https://nyxl.de/audioblindtest/testimages/demo02.png https://nyxl.de/audioblindtest/testimages/demo03.png Of course, if you want to make sure that you picked your favourite or could identify a certain audio file not just by chance but by actually hearing a difference, you need to do the test multiple times with the same audio files.
